Insulating plug

A removable insulation plug for plugging and replugging a hole formed in insulating material comprising:

• substantially flat circular seal body with upper and lower sides;
• handle means to allow hand grasping of said plug affixed to said upper side of said seal body;
• insulation affixed to said lower side of said body;
• vertical annular wall with inside and outside surfaces extending perpendicularly upward from and integrally attached to said body;
• first annular lip at the uppermost point of said wall, said lip extending angularly outward from and integrally attached to said wall;
• and
• plurality of additional annular lips disposed on said outside surface of said wall extending horizontally outward from and integrally attached thereto, said additional annular lips being disposed below, sufficiently close to said first lip and equal distances from each other so as to allow a tight seal to be maintained when said plug is in place.

• substantially flat circular seal body with upper and lower sides;
• handle means to allow hand grasping of said plug affixed to said upper side of said seal body;
• vertical annular wall with inside and outside surfaces extending perpendicularly upward from and integrally attached to said body;
• first annular lip at the uppermost point of said wall, said lip extending angularly downward and outward from and integrally attached to said wall;
• and
• second annular lip disposed on said outside surface of said wall extending horizontally outward from and integrally attached thereto, said second lip being disposed on said wall at a point above the lower most point of said first annular lip so as to allow a seal to be maintained when said plug is in place.
